What's Direct current (DC)

Direct current(DC)


Difference between alternating current and direct current

Direct current (DC) is a unidirectional flow of an electrical current. An Electric current is the flow of charges in any direction. If the flow of current is in one direction so it will be direct current dc. There is also another current flow known as alternating current. This type of current is opposite to the dc because an alternating current changes its direction periodically whereas the dc does not change its direction and, flow in one particular direction. Direct current has no frequency or we can say that it has a frequency of 0 Hertz, because it is unidirectional. Direct current can be produced or supplied to electrical circuits or machines by batteries and solar cells. Batteries are the best for supplying dc to circuits. Direct current is used in electronic devices with a battery to supply dc. DC power is widely used in low voltage applications charging batteries, automotive applications, etc.
